We had a number of electricity power supply glitches overnight. Plus another one just before 10am this morning.
I am not sure how widespread this was. Perhaps it was only our part of town.
It was a bit of a nuisance as our house was a bit like the Blackpool illuminations in the middle of the night.
Each time the power came back on again the light in our living room came on automatically. Plus the telephone handsets in our bedroom and living room pinged and lit up. Plus our speakers have lights on them. The lights on these were flashing for up to a minute or so before the speakers connected themselves back to the wifi and switched their lights off.
Hopefully the power supply will be back to normal now.
